Objectively evaluate a UI/web design against the pols.dev anti-slop design law: detect catalogued slop tells with cited evidence, score 8 weighted axes (color, type, components, layout, motion, execution, signature, cohesion), and emit a Slop Report with a 0–100 Slop Index and grade. Use when the user asks to "evaluate design slop", "slop report", "is this design AI slop", "audit this landing page design", "de-slop review", or wants an objective score of how generic/machine-made a design looks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Slop Eval Evaluate a design the way `skill-evaluation` evaluates a skill: every finding cites concrete evidence, every axis gets a 0–100 score, arithmetic runs through a script, and the output is a structured report — never a vibe check. The tell catalog lives in `references/tells.md`; read it before sweeping. The positive rubric (signature formula, cohesion checks, slop→premium pairs, and the "Adding Soul" guide) lives in `references/premium-markers.md`; read it before scoring Axes 7–8 and when writing fix prescriptions. The design context guide lives in `references/contexts.md`; read it to adjust priorities and tolerances based on the type of design being evaluated. ## Source - [The pols.dev anti-slop design law](https://pols.dev/slop.md) — the tell catalog, absolute rules, and signature formula are distilled from it. - Method modeled on [skill-evaluation](https://github.com/fabricioctelles/skills/tree/main/skills/skill-evaluation) (cite-or-cut, weighted axes, scripted scoring, failure-mode diagnosis). ## Parameters | Parameter | Description | Default | |-----------|-------------|---------| …

How to install
mdr add fabricioctelles/skills/slop-eval@sha256:c16f0c60c1bb90afThe line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
